PACTA for Investors
The Paris Agreement Capital Transition Assessment (PACTA) is an open-source and free of charge online software platform that enables users to measure the alignment of financial portfolios with climate scenarios as well as analyze specific companies.
How PACTA Works
PACTA compares what needs to happen in climate-relevant sectors in order to minimize global temperature rises with financial institutions' exposure to companies in these sectors. It uses a dynamic, forward-looking approach, based on the 5-year production plans of companies in a financial institution's portfolio.
The methodology measures alignment per sector or per technology, ensuring sector specific needs are included. For example, some sectors need to move more quickly than others; some need to reform (such as power generation); and others need to phase out (for instance, fossil fuels).

Portfolio Analysis Tool
The PACTA tool to analyze listed equity and corporate bond portfolios was relaunched in March 2021 with a new interactive format. For the first time, investors can now analyze multiple portfolios simultaneously, save their results online, and receive interactive results on their alignment with the Paris climate goals.
The tool is free to use, and requires a csv file including the ISIN, value and currency of the investment to run the analysis. For more information on how to format your portfolios for analysis, please see the Input User Guide. Input User Guide

About This Tool
PACTA was originally developed by 2° Investing Initiative (2DII) with backing from UN Principles for Responsible Investment. In June 2022, 2DII transferred stewardship of PACTA to RMI, formerly Rocky Mountain Institute. In 2024, the PACTA for Investors tool was modernized by Silicon Ally, a software development non-profit. The code for this tool, as well as the analysis code for PACTA is open source. Learn More About PACTA
